Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 4-644611-1 is determined by alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 11
• Number of Rows: 1
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 1 Wall
• Fastening Type: Friction Lock
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

The Molex 0026482115 connector satisfies all mandatory matching parameters, establishing it as a valid substitute part. Both connectors share identical pitch spacing, position count, mounting methodology, and termination approach. Both maintain UL94 V-0 flammability compliance and MSL Level 1 moisture sensitivity classification, ensuring compatibility in equivalent application environments.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 4-644611-1 and Molex 0026482115 connectors maintain Active product status and satisfy UL94 V-0 flammability requirements and MSL Level 1 moisture sensitivity classification. The TE Connectivity part carries RoHS Compliant certification, while the Molex part carries ROHS3 Compliant certification, both meeting current regulatory compliance standards.

The primary differences between these parts are non-critical to substitution eligibility:

Contact Post Length Variation: The Molex 0026482115 features a longer contact post (0.172" versus 0.125"), resulting in a 0.050" increase in overall contact length (0.750" versus 0.700"). This difference accommodates varying printed circuit board thicknesses and does not prevent functional substitution in standard through-hole applications.

Contact Finish Composition: The TE Connectivity part utilizes tin contact finish on mating surfaces, while the Molex part utilizes gold. Both finishes provide adequate electrical conductivity and corrosion resistance for general purpose and industrial applications.

Insulation Material Composition: The TE Connectivity part uses thermoplastic glass-filled material, while the Molex part uses polyester. Both materials satisfy UL94 V-0 flammability requirements and provide equivalent mechanical and electrical insulation properties.

Contact Base Material: The TE Connectivity part uses copper alloy contacts, while the Molex part uses brass contacts. Both materials provide equivalent electrical conductivity and mechanical durability for friction lock fastening applications.

Selection between these parts is determined by application-specific requirements regarding contact post length, board thickness accommodation, and material composition preferences. Both parts are suitable for direct substitution in equivalent electrical and mechanical application contexts.

Frequently Asked Questions (FAQ)

Q: What determines whether the Molex 0026482115 can substitute for the TE Connectivity 4-644611-1?

A: Substitution is based on matching critical parameters: connector type (Header), contact type (Male Pin), pitch spacing (0.156" / 3.96mm), position count (11), row configuration (1), mounting method (Through Hole), termination type (Solder), shrouding style (Shrouded - 1 Wall), fastening mechanism (Friction Lock), contact shape (Square), and compliance certifications (UL94 V-0, MSL Level 1). Both parts satisfy all these criteria.

Q: Does the difference in contact post length affect compatibility?

A: The Molex 0026482115 features a 0.047" longer contact post (0.172" versus 0.125"). This difference accommodates thicker printed circuit boards and does not prevent functional substitution. Application-specific board thickness requirements determine whether this variation is beneficial or requires consideration.

Q: Are the different contact finish materials (tin versus gold) significant for substitution?

A: Both tin and gold finishes provide adequate electrical conductivity and corrosion resistance for general purpose and industrial applications. The choice between these finishes is determined by application-specific requirements regarding contact resistance, environmental exposure, and cost considerations. Both finishes are compatible with friction lock fastening mechanisms.

Q: What is the significance of the different insulation materials?

A: The TE Connectivity part uses thermoplastic glass-filled material, while the Molex part uses polyester. Both materials satisfy UL94 V-0 flammability requirements and provide equivalent mechanical and electrical insulation properties. Material selection is determined by application-specific environmental and mechanical requirements.

Q: Do the different RoHS certifications affect substitution eligibility?

A: The TE Connectivity part carries RoHS Compliant certification, while the Molex part carries ROHS3 Compliant certification. Both certifications meet current regulatory compliance standards for restricted substance usage. Both parts are suitable for applications requiring RoHS compliance.

Q: What is the difference between the MTA-156 and KK396/41671 series designations?

A: These designations identify the connector series from their respective manufacturers. The MTA-156 series is TE Connectivity's designation for 0.156" pitch connectors, while KK396 and 41671 are Molex series designations for equivalent 0.156" pitch connectors. Series designation does not affect substitution eligibility when all electrical and mechanical parameters align.

Q: Are both parts suitable for industrial and general purpose applications?

A: Both the TE Connectivity 4-644611-1 and Molex 0026482115 are rated for general purpose and industrial applications. The Molex part additionally lists automotive, medical, and telecommunications applications. Both parts operate within equivalent environmental and electrical specifications for standard industrial use cases.

Q: What packaging considerations apply to these substitute parts?

A: The TE Connectivity 4-644611-1 packaging information is not specified in the provided data. The Molex 0026482115 is supplied in Bulk packaging. Packaging format does not affect electrical or mechanical compatibility; it determines only the quantity and presentation method for component procurement and handling.
